Dyno Numbers.....I Think

Thanks Paul

I think I've seen you say you are runnin the t4m0 setup with your EEC Tuner.

I'm gonna poke around in that file and use your provided ect for a bit of research.

I gotta think by the time you clean the tires, the enrichment would not be in place.

When we were kids and at the strip every time it was open. We used to push our old cars to the line and would not fire em up until the starter yelled and shook his fist at us

Yes Grady, I am still running the T4MO setup. What do mean by enrichment?


If my buddys are around we push the cars around in the lanes so as to not heat them up too!

They get pissed though when two of your buddies are going heads up and the other two of you are running back and forth between lanes so as to push them both so that they line up together...

OK Paul

A short story to show how I learned something new

A good while back there was this guy who sent me his dlogs from one of those 3 pulls for 65 bux kinda deals.

He was puzzled and bummed out about why his first pull was the worst of all three even though he had let his car cool down a lot before the session.

I quickly saw he was a good bit more fat on the first pull
and
pull number 2 & 3 were about the same

After he finally gave me specific details of what happened for the entire session, here is what I found out

He scheduled himself for a day he could be first on the dyno right after they opened in the morning. His reasoning was he could arrive early and cool down his car.

He did just that ... but ... after they got his car on the rollers, something happened to delay things for about 30 to 45 more minutes with the fan blowing on the motor all that time.

Since his car was already fairly cool and with the delay and all ...............

When the first pull was made ... he had startup enrichment in place which resulted in a ratio so fat ... it hurt his numbers. Pulls 2 and 3 were almost back to back and everything was normal for those pulls thus producing the leaner ratios.

I know the data don't tell no lies
but
When I first suspected that little theory

I did in fact play around with the fuel table, ect's, and startup time
to verify that my suspicions were exactly what happened to that guy

Hey ... after all

To suspect ............ is one thing
To know ................ is more better
